• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - canh tranh tuan ((dung hong) OR (duong hong)) anh ((tuan cu) OR (tuan tu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - canh tranh tuan ((dung hong) OR (duong hong)) anh ((tuan cu) or (tuan tu))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - canh tranh tuan ((dung hong) OR (duong hong)) anh ((tuan cu) or (tuan tu))*.
